Abstract:
In one embodiment, a method comprises: receiving, by a parent network device in a directed acyclic graph (DAG) network topology, a data packet destined toward a DAG root and having been output by a target device in the network topology; identifying, by the parent network device based on the received data packet, an identifiable condition for caching a downward path enabling the parent network device to reach the target device independent of any route table entry in the parent network device; and caching, in the parent network device, the downward path enabling the parent network device to reach the target device independent of any route table entry in the parent network device.
